Russian Standard Gate Valves refer to gate valve products that comply with Russian national standards. These valves strictly adhere to relevant Russian standards during design and manufacturing to ensure product quality and performance. Russian Standard Gate Valves typically feature high pressure resistance and excellent sealing properties, making them suitable for pipeline systems handling various high-pressure, high-temperature, and corrosive media.
Material and Standards
The Russian standard gate valves are available in various materials, including cast iron and stainless steel. For instance, components such as the body, cover, and bracket are often made of materials like WCB, A105, and Cr5Mo, while the gate plate and valve stem commonly use materials such as 25Cr2MoV and 1Cr18Ni9Ti. The selection of these materials ensures the stability and durability of the gate valves under harsh conditions.
Structural Configuration and Application Scenarios
Russian standard gate valves come in various structural designs, with the most common being wedge gate valves and parallel gate valves. Their sealing surfaces can be self-sealed by the pressure of the medium, meaning the medium pressure pushes the gate plate towards the valve seat to achieve sealing. This design allows Russian standard gate valves to perform exceptionally well under conditions where they are not frequently opened or closed and are kept fully open or closed. However, they are not suitable for use with high-velocity flowing media or in situations requiring flow regulation, as partial opening may cause vibration and wear.
Performance Parameters & Application Fields
Russian standard gate valves are widely used in pipeline systems across industries such as oil, chemicals, power, and metallurgy. Their excellent corrosion resistance and high strength allow for long-term stable operation in harsh environments of these industries. Additionally, Russian standard gate valves offer benefits such as low flow resistance and easy operation, making them suitable for pipeline systems handling various high-pressure, high-temperature, and corrosive media.
